T0 all whom it may concern:

Be it known that I, WrLLL-iai BlmwAn'ri-I, a citizen of the United States of America, and resident of Gary, in the county ef-Deuel and State of South Dakota, have invented certain new and useful Improvements in Automobile Springs, of which the following is a specification.

This invention relates to springs for Ford automobiles and has for its object the provision of a novel spring and an arrangement for its attachment to Ford automobiles now in common use, by which the length of the spring as compared with those ordinarily employed on Ford automobiles is increased and whereby the action of the spring is improved in that it increases the comfort of the occupant of the automobile.

It is a further object of this invention to produce a spring of the character indicated which will operate as a shock absorber by reason of the presence of scroll formations at the ends of the springs at their junctions with the shackles by which the springs are connected to the spring perches.

A still further object of this invention is to produce a spring having qualities indicated while at the same time it is strong and durable and the leaves thereof are held in assembled relation to each other so as to prevent their dissociation.

With the foregoing and other-objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawing forming part of this application wherein like characters denote corresponding parts in the several views, and in whichigure 1 illustrates a front elevation of a spring applied to the front axle of a Ford lowerleaf terminates in an eye 9 at each end by which it is connected to the shackles l0 pivotally connected to the spring perches 11, which spring perches are of the ordinary Ford type slightly differently situated in that the curved ends extend outwardly instead of inwardly as they do when operating in conjunction with the ordinary type of Ford springs. In this form of the invention, the lowermost leaf reinforces the scroll at either end and it results in strengthening the structure without materially interfering with the spring action of the leaves.

It is furthermore shown that the formation of the scroll results in the production of a clearance between the lowermost leaf and the spring perches, a condition which permits movement of the spring without liability of its abutting the spring perches unless the load is abnormal.

It has been found that a spring made in accordance with this invention can bereadilyapplied to Ford automobiles now in common use by the simple expedient of an adjustment of the spring perches in the main ner indicated, so that the conversion can he expeditiously accomplished without supplying any new parts except the spring itself.

I claim:

1. In a spring for Ford automobiles, a plurality of superimposed leaves connected together at their centers, the next to the last leaf having scroll form terminating under the spring, the lowermost leaf having its end shaped to the configuration of the scroll, and means for attaching the spring to spring shackles.

2. In a spring for Ford automobiles. spring perches having outwardly curved ends, a spring having its end terminating in a scroll bent under the spring, the said spring comprising a plurality of leaves next to the lowermost of which has the scroll formation for attachment to a scroll and the lowermost of said leaves being shaped to the configuration of the scroll and reinforcing the same, and means for holding the leaves in assembled relation to each other.

3. The combination with an axle having two rigid posts, of a leaf spring, the major leaf of which is provided at its ends with return bends extended beyond the posts, and links connecting the return bends to the posts.

' 4. The combination with an axle having two upright rigid posts, the upper ends of which are outwardly offset in opposite directions, of it leaf spring, the major leaf of which is provided at its ends with downwardly extended return bends extended beyond the posts and links connecting the i0 ends of said posts being curved outwardly toward the en ds of said axle, a leaf spring secured to the body of a vehic1e disposed above said axle and extending longitudinallyv thereof, said spring being curved downwardly to'svard said axle and having the ends thereof provided with dovvn wsurdi extending return bends extended beyond the posts, and links connecting the return bends to the posts.
